Description

Technical Field

[0001] The utility model relates to the technical field of ball-jointed drum couplings, in particular to a ball-jointed drum coupling. Background Art

[0002] The ball joint drum coupling is a special coupling, which is mainly used in mechanical equipment in the fields of lifting equipment, ships, metallurgy, electric power, etc. to realize the connection between the reducer driving shaft and the driven shaft of the wire rope drum or other similar components. However, the driving shaft and the driven shaft are directly attached to the inside of the ball joint body. During operation, the gap expands due to the increasing friction, which affects the transmission efficiency. The ball joint body needs to be replaced to restore the performance.

[0003] The publication number is CN219413315U, and a reel coupling is provided. The utility model discloses a reel coupling in the field of couplings, and the reel coupling is provided. The reel coupling comprises an upper connecting seat, a lower connecting seat and a ball joint. The reset spring is squeezed by the movement of the movable plate, and the fixed column is driven to move, so that the fixed column is withdrawn from the fixed hole, thereby releasing the fixation of the clamping plate, and the connecting ring is disassembled, so that the upper connecting seat is separated from the lower connecting seat, which is convenient for placing the ball joint into the connecting seat, facilitating the installation and replacement of the ball joint, avoiding the overall replacement of the coupling, saving costs and improving convenience.

[0004] However, the above patent uses a return spring to fix the clamping plate. Although the connecting ring can be disassembled quickly, it is not stable under high-speed rotation or large torque. Therefore, a ball-jointed drum coupling is proposed. Utility Model Content

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a ball-jointed drum coupling, comprising a connecting flange, connecting seats are fixedly arranged on both sides of the connecting flange, a fixing block is fixedly connected to the connecting seat, the fixing block is rotatably connected to a threaded rod, the threaded rod is threadedly connected to a threaded block, the lower end of the threaded block is fixedly connected to an L-shaped limit frame, a fixing disk is provided on the outer side of the connecting seat, the fixing disk is fixedly connected to the connecting block, a limiting hole is provided on the connecting block, a socket is provided on the connecting seat, the connecting block slides inside the socket, and the L-shaped limit frame slides inside the limiting hole.

[0007] As a further description of the above technical solution: the connecting seat is provided with two upper and lower ones, and the middle sleeve of the two connecting seats is provided with a ball seat.

[0008] As a further description of the above technical solution: the connecting seat is provided with a guide groove, and the L-shaped limiting frame is slidably connected inside the guide groove.

[0012] As a further description of the above technical solution: the fixing disk and the connecting seat are tightly fitted and are arranged through.

[0013] The utility model has the following beneficial effects:

[0014] 1. In the utility model, the L-shaped limit frame is disengaged from the limit hole through the rotation of the fixed block and the rotation of the threaded block, and the ball seat can be quickly replaced without additional tools.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1

[0023] Reference Figure 1-Figure 4 As shown, a ball joint reel coupling comprises a connecting flange 1, which is convenient for installing the coupling and the connecting piece. Connecting seats 10 are fixedly arranged on both sides of the connecting flange 1. A fixing block 2 is fixedly connected to the connecting seat 10. The fixing block 2 is rotatably connected to a threaded rod 3. The threaded rod 3 is threadedly connected to a threaded block 4. The lower end of the threaded block 4 is fixedly connected to an L-shaped limiting frame 6, which is convenient for clamping the connecting block 8 on the connecting seat 10. A fixing plate 7 is arranged on the outer side of the connecting seat 10. The fixing plate 7 is fixedly connected to the connecting block 8. The connecting block 8 is provided with a limiting hole 9. A socket 11 is provided on the connecting seat 10, the connecting block 8 slides inside the socket 11, and the L-shaped limit frame 6 slides inside the limit hole 9. The L-shaped limit frame 6 is disengaged from the limit hole 9 by rotating the fixing block 2 and the threaded block 4. The ball seat 13 can be quickly replaced without additional tools. Compared with the fixing method using a buckle or a spring, the ball-hinged drum coupling is more stable by using a threaded rod 3 for fixing, and can maintain a tight and reliable connection even in the case of high-speed rotation or under large torque.

[0024] The connecting seat 10 is provided with two upper and lower ones, and a ball seat 13 is provided in the middle sleeve of the two connecting seats 10. The connecting seat 10 is provided with a guide groove 5, and an L-shaped limit frame 6 is slidably connected to the inside of the guide groove 5. There are two fixed disks 7, and each fixed disk 7 is provided with two connecting blocks 8, and the two connecting blocks 8 are arranged in parallel. The guide groove 5 and the socket 11 are connected and vertically arranged. The radius of the limit hole 9 is equal to the radius of the socket 11. The fixed disk 7 and the connecting seat 10 are tightly fitted and connected.

[0025] Working principle: the staff rotates the threaded rod 3, and the rotation of the threaded rod 3 causes the threaded block 4 to move, and the threaded block 4 drives the L-shaped limit frame 6 to slide inside the guide groove 5 until the L-shaped limit frame 6 slides out from the inside of the limit hole 9, and then the fixed disk 7 is separated from the connecting seat 10 by hand until the connecting block 8 is completely disengaged from the inside of the socket 11, and then the two flanges are separated to take out the ball seat 13. At this point, the ball seat 13 can be quickly replaced. Compared with the existing disassembly method using buckles or springs, the ball hinge reel coupling has a more stable connection method between the connecting seat 10 and the fixed disk 7 after taking into account the rapid replacement of the ball seat 13.

[0026] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
